[Name] ACTIVECHECK

[Description] A version of the checkbox that can optionally disable other
              parameters when checked or unchecked, similar to ACTIVECHOICE.
              
               - When box is checked, the types controlled by macro names in
                 <macroNamesChecked> will be disabled
               - When it is unchecked, the macro names in <macroNamesUnchecked>
                 will be disabled.
               - <macroName> will be set to <checkedValue> or <uncheckedValue>
                 depending on the state of box when GUI setting box returns.
               - <checkedValue> and <uncheckedValue> can be any arbitrary string
                 not just "yes" or "no".
